Abstract

본 발명은 자동차의 브레이크드럼 방열구조에 관한 것으로, 더욱 상세하게는 차축과 함께 회전하는 드럼 내측에 선택적으로 제동을 이루는 드럼식 브레이크에 있어서, 상기 드럼에서 발생하는 고열을 냉각시키는 방열핀 구조의 개선에 관한 것으로서, 차축(10)에 고정되어 회전하는 드럼(20)과, 드럼내주연에 접촉하여 제동을 이루는 브레이크슈우(30) 및 브레이크라이닝(32)을 구비하고, 상기 드럼(20)주연에 반경방향 외측으로 돌출구성되어 브레이크라이닝(32)과 드럼(20)의 마찰열을 외부로 방출하는 방열핀(22)을 드럼(20)주연 및 상기 테이퍼면(24a)에 걸쳐 나선형으로 구성됨을 특징으로 한다.The present invention relates to a brake drum heat dissipation structure of an automobile, and more particularly, to a drum type brake for selectively braking inside a drum that rotates together with an axle, to improve the heat dissipation fin structure that cools high heat generated in the drum. And a drum 20 which is fixed to the axle 10 and rotates therein, a brake shoe 30 and a brake lining 32 which come into contact with the drum inner circumference and brake, and radially around the drum 20 circumferentially. The heat dissipation fin 22, which protrudes outward and discharges frictional heat between the brake lining 32 and the drum 20 to the outside, is helically formed around the drum 20 and the tapered surface 24a.
